d.
within the vessel such as a supporting beam which would
interfere with the sound path between the transducer and
the material being measured.
NOTE
Ultrasonic sound waves are radiated from the face of the
Transducer within a cone of approximately 8 degrees. The
Level Genie System depends upon these sound waves reaching
the surface of the material to be measured and being re-
flected back along this same "sound path". Any object
within this "sound path" that reflects an "echo" will
interfere with the measurement of the material level.
For practical purposes the transducer should be located
one half bin radius from the side wall (assuming a center
fill bin.1
Position the transducer so that its radiating surface is
aimed directly at the material to be measured. When
measuring liquids, the radiated beam or sound path must
be perpendicular to the liquid surface.
